ADT has been a leader in home security for decades, but its lengthy contracts are a turnoff for a lot of people. ADT has six redundant monitoring centers to make sure you're never without help in an emergency, and its longstanding experience in the security field is a definite plus.
ADT has five monitored plans with all the essentials and some add-ons to boot. It also gives you the option for a landline connection if you live in an area with poor cell reception. Like Vivint, ADT offers live video, app control, and home automation, but you might pay a bit more for these features. The equipment that comes with ADT's cellular plans are Z-Wave and Alexa compatible, so you can control your system with your voice.
No matter what kind of system you choose, you'll have to sign a monitoring contract with ADT before your system is installed. Contracts are for a minimum of three years, and you'll also have to pay for the cost of leasing the equipment up front. One standout feature of ADT's contracts is the six-month money-back guarantee—if you decide you don't like your system or service, you can cancel it at any time within six months after you sign the contract (certain restrictions apply). ADT will refund any monitoring fees.
